Toall, whom itmmly concern.:

.-Be it known that l, CHARLES F. W. MAN- 'ZEL, a citizen of. the United States, residing at Buffalo, in the county of Erieand State of New Yorlc, have invented certain new and useful Improvements in Devices for Converting Mot on,of which the following is especicstion.

My invention relates to 'an improved oilpump; and the objects of the invention are to provide e simpre and'convenient feeding device therefor and a simple and convenient' Ineens for regulating the feed. It also relates to certain details in coustruetion of the oil-pump and its operating mech-.

auism, all of which will be fully and clearly hereinatter described and claimed, reference elevation of th annular internelly-grooved.

ring and its operating-clutch. Fig. 4 represents an edge View of the anged disk and its annular grooved ring and the operating clutch mechanism.' Fig. 5 represents e de tached section of the clutch mechanism onf o r about line aa, Fig. 3. Fig. Gis a detached View o the slotted com.

.In referring to the drawings in detail like numerals represent like parts.'

lrepresen ts the frame, which is'of the usual iron construction and is provided at one end with an upright 2, having boxes 3, in which the forward end of the plunger-sha1" t 4 is supported. The oil-cup is supported at the opposite end of the frame, the cup port-ion 4 being pro vided with a downwzirdly-extending portion 5*, which passes through an opening in the frame and is rigidly secured in placeby the lock-nut 6. A tubular `portion G extends horizontally through and outwardly a short distance on each side of the flanged part of the cup being preferably formed integral with said cup. The longitudinal opening 7,

'extending through the tubular portion, forms a supporting-slideway for the forward end of. the plunger 4. To limit theiorward stroke of the plunger, the opening reduces in circumference, forming@ shoulder 7, against werd stem '12,

spring 13, sei-d spring 13 serving to normally vvh ich theend of the plunger shuts. The rc1 duced opening 85 enlerges againto forme valve-chamber 9, in which e vlvedevice ,10 is placed,he.ving s, rearwardly-extending stem 11," projecting into the reduced opening 8. The valve device 10 also has u forvrhicll is encircled by a.- spiral maintain the valve in a closed position. A' transverse opening 1e* entends -through the side of the tubular portion and slords spas-- sage fox-,the oilinto the longitudinalopening?.

.The forward end oi' the tubular portion 6,

through which the plunger passes, is provided with a packing device comprising an elastic washer 15, which eneircles the plunger, and thescrew-cap 16 screws upon the end of the portion G, (see Fig. 1;) thus preventing the escape of oil. Thecylinder 5 of the cap,

which' is preferably formed of gless or similar transparent material, is supported in the 1Q of the rotating disk 1 1 is adapted totravel, and has extensions 9, provided with un opening through which the plunger 4 passes. The

cam issecu red. to the plunger at an y position to which it may be adjusted longitudinally by the locking-screw 1?".

To lessen the friction', the 'crank pin is provided with a looselyencircling annular ring` 12.

The device is also provided with srv-brake mechanism comprisinge curved brake-spoon 13, having the interior ings 14 and the leather portion 15. scoured to the frame 1 by e screw or bolt 16,

`thus allowing a. range of pivot-al movement sufficient to allow it to enter into or withdraw from frictional contact with the periphery o the disk 11. The crank-disk 11 is rigidly mounted upon a .shaft 17, which is supported in boxes upon the frame, and a second disk 13 is also rigidly mounted upon the shaft 17, which is provided with a. laterally-extending circuler flange forming an annular ring 19, the interior of which is provided with e. groove 20, preferably V-shaped in cross-section, in which the clutch-block 21 is adapted to travel.

The clutch-block 21 in actuated by evibre- 'flanged top edge of the portion 4. A cam 8 is provided with a slot, in which n erzhlt-piu'4 This brekespoon is preferably tile arm 22, which is loosely hung at one end from the shaft 17, so as to rotate freely thereon. It is provided with a longitudinal slot 23, and a connecting-rod 24 is pivoted at 5 one end to thc clutch-block by means of the screw or bolt 25, and a screw-bolt 26 is passed through the opposite end and through the slot 23. (See Fig. 3.)

By referring to Fig. 3 it will be seen that a movement of the vibratile arm in one direction' will canse the clutch-biock to freionally 'engage `with or grip against the interior of the groove 20, thus rotating the disk 1S and its shaft 17, and that a movement in the opposite or reverse direction will move the clutchblock without rotating the disk. The direction of the rotation of the shaft can be changed by moving the clutch-block to the opposite side of the vibratile arm, and the tension of the grip of the clutch-block upon the interior of the grooved annular ring can be regulated to a certain degree by varying thc angle of inclination from the center byineans of xuoving the bolt 26 in the slot 23.

the clutch mechanism the reciprocating movexnent of the vibratilc arm is converted into an intermittent rotary movement cf the shaft, and that is in turn converted into a reciprocating movement of the plunger by means of the slotted cam and crank-disk. Y

The shaft can be rotated by hand, if dcsircd, by fitting a crank or similar tool upon its square end 27. l

The camSis longitudinallyadjustablc upon the plunger to regulate the position of the plunger iu its'slideway and adjust it relatively to the feeding channel or opening 14,

The screvcbolt 17 serves to fasten the cam to the plunger at any position to which it may bo adjusted.

As the bolt '2G is longitudinally adjustable in the slot :23, the angle of the clutchblock with respect to the operating-arm can be Varied to take up the wear of the opposing surfaces for the clutch-block and the grooved portions of the ring or to adjust the block to obtain a better gripping effect.

1 claim as my invention- 5o l., A device for converting a reciprocating Vdisk rigidly mounted upon said shaft and By menus of the annular grooved ring and movement into au intermittent rotary move' n1ent,c0mprisi ng an internally-groovcd anun lar ring rigidly mounted upon a. shaft, a reciprocating arm vloosely suspended from the same shaft and having a longitudinal slot, a cl1itclr-biock adapted to fit and travel in tho groove in the ring, a rod pivot-ally connected at one end to the clutch-block and a bolt. passing through the opposite end of the rod and the longitudinal slot in the arm, and adjust 6o able in said slot to vary the position of the lutlch-bloek with respect to said arm, as set OIt l.

2.

3. In an oil-pump, the combination with the pump, of a plunger, a slotted cam mounted on said plunger and adjustable longitudinally thereon, a shaft, a disk rigidly secured to said shaft and having ac rank-pin adapted to travel in the slot in the cam, au annular ring also rigidly secured to said shaft, a clutch-bioek adapted to operate in said ring, a reciprocating arm for operating said clutchblock and means for adjusting said clutch to vary the angle of inclination withA respect to said arm, as set forth. f
